The Allen-Bradley 1784-PCIC, also cataloged as the 1784-PCIC ControlNet PCI Communication Card, operates as a dedicated hardware component for PC-based ControlNet network communication within Allen-Bradley industrial control platforms.

Model Configuration Details

The 1784-PCIC is a PCI communication interface card designed to provide ControlNet connectivity between a personal computer and Allen-Bradley automation systems. The card supports ControlNet messaging, PLC-5 communication functions, and VNET bus messaging through PCI-based computer architectures.

The module supports installation in compatible PCI and PCI-X expansion slots and provides ControlNet network access through a BNC interface.

Hardware Specifications

Industrial Network Communication Characteristics

The 1784-PCIC provides PC-based access to ControlNet deterministic networks through PCI bus communication. The card supports data exchange between computer applications and Allen-Bradley control systems using ControlNet messaging services.

Allen-Bradley industrial communication platforms use dedicated network interfaces to maintain data exchange between controllers, programming systems, and distributed I/O devices. The 1784-PCIC enables integration of PC applications with ControlNet-connected PLC systems.

The module uses PCI bus communication architecture and requires compatible software drivers for configuration and application-level communication. Firmware and driver compatibility must match the installed operating environment.

ControlNet Network Interface Operation

The 1784-PCIC provides a physical ControlNet connection through a BNC interface. Network wiring should maintain correct coaxial cable termination, shielding, and grounding practices.

The PCI interface supports installation in multiple computer expansion architectures, including 5 V PCI, 3.3 V PCI, 32-bit PCI, 64-bit PCI, and PCI-X slots.
